Summary
Total hip arthroplasty effectively corrects limb length discrepancy (LLD) in patients with hip arthritis. This surgical approach significantly improves function and reduces disability associated with LLD.
Area of Science:
- Orthopedic Surgery
- Hip Reconstruction
- Limb Deformity Correction
Background:
- Limb length discrepancy (LLD) combined with hip arthritis causes significant disability, including gait impairment and low back pain.
- Total hip arthroplasty (THA) is a primary treatment for hip osteoarthritis, with LLD correction being a key surgical goal for functional outcomes.
Purpose of the Study:
- To evaluate the effectiveness of primary total hip arthroplasty (THA) combined with soft tissue releases in treating hip arthritis with significant limb length discrepancy (LLD).
Main Methods:
- A prospective clinical case series involving 23 patients with hip arthritis and a true LLD of 2 cm or more.
- Patients underwent primary THA with additional soft tissue releases.
- Preoperative and postoperative outcomes including LLD, range of motion (ROM), pelvic obliquity, and Harris hip score (HHS) were compared at a minimum one-year follow-up.
Main Results:
- The mean Harris hip score (HHS) improved significantly from 41 to 88.4 one year postoperatively.
- Mean limb length discrepancy (LLD) was reduced from -3.1 cm to -0.1 cm.
- Pelvic obliquity decreased from 11 patients preoperatively to only one patient postoperatively, with no reported nerve palsy.
Conclusions:
- Primary total hip arthroplasty (THA) with adjunctive soft tissue releases is a successful treatment for hip arthritis accompanied by supratrochanteric LLD.
- This combined surgical approach effectively corrects LLD and improves functional outcomes in patients with hip arthritis.
